MATLAB实现GTD模型下基于MUSIC算法的目标散射中心提取与回波仿真

上传者: eee77 | 上传时间: 2026-04-08 19:43:22 | 文件大小: 6.1MB | 文件类型: ZIP
提供一套完整的MATLAB工具集,用于模拟雷达目标回波信号并提取其散射中心位置。核心算法基于几何绕射理论(GTD)建模目标电磁散射特性,并采用MUSIC(Multiple Signal Classification)方法进行高分辨方向估计,从而定位目标表面主要散射点。程序支持多种典型目标结构的建模与仿真,输出包括时域/频域回波数据、散射中心坐标及对应幅度信息。配套包含2D-ESPRIT算法实现、AIC准则信源数估计、FFT/IFFT信号处理模块、SAR回波生成函数(sar_echo.m)、以及多份参考文档和论文代码(如王菁论文相关实现)。所有脚本均可直接运行,适用于雷达目标识别、ISAR成像预处理、散射特征库构建等研究场景。
